Question 870992
Let the width  be x															
..															
Length   of	rectangle		12	feet											
width of  	rectangle		8	feet											
															
Area =			96		m^2										
Area of 	plot		192	m^2											
length of 	rectangle	&	plot				12	+	2	x 					
width of	rectangle	&	plot	8	+	2	x								
															
(	12	+	2	x	)	(	8	+	2	x	)	+	-96	=	192
															
	96	+	24	x	+	16	x	+	4	X^2		+	-96	=	192
	4	X^2		+	40	x		-192	=0					
4x^2-16x+56x-192=0

4x(x-4)+56(x-4)=0

(x-4)(4x+56)=0
x=4 OR -14
ignore negative

width = 4 feet
